rust-cpython: don't swallow the dirstate error message

In case we do get a dirstate error, we want to get the full error message and
not just an opaque `Dirstate error`.

# extension to emulate interrupting filemerge._filemerge


from mercurial import (
    error,
    extensions,
    filemerge,
)


def failfilemerge(*args, **kwargs):
    raise error.Abort(b"^C")


def extsetup(ui):
    extensions.wrapfunction(filemerge, 'filemerge', failfilemerge)
